This is arranged to be tripped by a dog 29 pivotally mounted on a rod 21 supported by upstanding lugs on the bottom II and shown in Fig. 7 as4 y connected through a link 2B tov an operating' derstood that when the operating handle 29 is depressed by the operator, the clutch is released and asingle revolution imparted to the shaft 22. This, in turn, operates through the Geneva motion and indexes the cylinder I4 of the turret through 60.

The illustrated machine is shown as provided with six work pressing units, although it may be desired to include any convenient number. The cylinder I4 is provided with six outwardly extending radially disposed arms 3I in the form of vertical plates each carrying at its outer edge a fiat base plate 32 disposed at an angle of approximately 45 `to the horizontal. Each base plate is provided with a central longitudinal slot 33, as shown in Fig. 8, and serves as a support and guide for a rectangular box 34. Each box has a downwardly extending lug at its lower outer edge through which passes an adjusting screw threaded into a corresponding lug on the bottom of the base plate 32. Each box has hooked lugs at its side edges which extend over the bottom of the base plate 32 so that the latter acts as a guide and permits longitudinal adjustment of the box 34 thereon. Each of the boxes is provided with flanged side walls and these enclose an iniatable pad 36 of rubber, leather or flexible composition which is adapted to shape itself automatically to Y'the bottom of the lasted shoe and conform the'outsole thereto when inflated. A flexible hose 3l' extendsr through the slot 33 in thebase plate 32 and makes a pressure connection through the bottom of the base 34 with the iniiatable pad 36. Each hose 3l is connected to the outer end of a pipe 38 which extends radiallyr from the cylinder I4. In each of the pipes 38 is included a controlling valve operated by a sliding sleeve, 4D. The sleeve is shifted to open or close the valve by a cam karm k4I having a roller 42 atits inner end and' being pivotally mounted in a bracket 39 depending from each of the pipes 38. The valve, operating arm ``4I is shifted to and held in its open position by the action of a circularycam 43 fast on the top I2 of the machine v frame in proper positionto engage the roller 42 of the arm. An angular abutment 44 is arranged to engagethe top of thefbracket 39to guide and Asupplortthe outboard portion `of 'each of the .pipes 3 8fintheir,rotaryfrnovernent with the cylinder ,I 4. i

j fefvalvefarm 4I may be operated manually.V at

anytimetolclose the valve, orit may be operated infthe iinal station of the machine by a yertical rod 45 located within Athe cylindrical frame IIJ and connected at its lower end to a treadle 46. .A iiuid pressure supply pipe 41 passes through the Geneva disk il and is threaded into the bottom I 6 ofthe cylinder I4. It is connected through a swivel joint 48 to any convenient source of iiuid pressure as, for example. to` an air compressor.: Through this inlet connection full iiuid 4 pressure is maintained at all times within the chamber of the cylinder I 4.

The upper end of the cylinder I4 is closed by a head 50. A sleeve 5I is telescopically mounted upon the upper end of the cylinder I4 and together with a disk 52 forms a head or the hub of a spider vertically adjustable by means of a hand .wheel ,53. having .a stem threaded. into the head 59 of the cylinder. The sleeve 5I is confined to vertical movement on the cylinder I4 by slot and stud connection therewith and carries six radially disposed arms 54. These arms are curved and extend over the pads 36 but are narrow so that they do not obstruct the operators view oi' the work. Each arm 54 carries a pivoted toe post 55' and a vpivoted heel post 56. These are arranged to bear upon the forepart of the lasted shoe 69 and the cone of its last and support the work against the thrust of the iniiated pad.

In the normal operation of the machine the operator stands at its left hand side as shown in Fig. 1. VThe pad opposite to him will have been deflated bydepression of theV arm 4I which has moved the valve 49 to its outer positionr and opened the exhaust port 49. vThe operator is therefore free to present tothe machine 4a lasted shoe having its outsole spotted in proper position in the shoe bottom. The deflated pad provides sufcient clearance for insertion of the lasted shoe beneath the toe and heel posts as indicated at the left in Fig. 6, and if adjustment is necessary this is conveniently eiected by manipulation of the adjusting screw 35.

Having properly positioned the shoe, the 0D- erator first depresses the foot treadle 46 to inflate the pad, whereupon the pad is at once iniiated and the shoe bottom subjected to the full fluid pressure ofthe system. He then depresses the starting handle 29 whereupon the turret is indexed in a counterclockwise direction. The operator now proceeds to load each pressure unit as it comes to him with a lasted shoe and sole, and in each case the work is held under iiuid pressure during the full revolution of the turret. HAt theconclusion of each full revolution the pad arriving before the operator has been automatically deflated by action of the deiiating cam 43.

The valve controlling sleeve 49 uncovers the exhaust port 49 when the valve is moved to its deflating position as shown in Fig. 8. After the cam roll 42 leaves the deating cam 43, the valve sleeve may be moved to iniiating position in which the exhaust port 49 is closed. While the pad ordinarily remains inflated with the shoe under pressure during a turret rotation of approximately 320, any selected pad may be defiated at any ofthe ve intermediate stations by depressing the cam arm 4I as an emergency opleration.V

It will be apparent that the angle of the jacks is such thata single vertical adjustment of the head52 will automatically positionthe toe posts at each pressure unitfor an entire range of shoe sizes. In changing the machine to handle .shoes of any given size, it is necessaryfor theoperator to adjust properly. for a single shoe atV the initial station, and lbyso`v doing he has takencare offallsix pressurey units. l y
